METHOD OF WORK OF LENS TRAFFIC LIGHT WITH DOUBLE-STRANDED LAMP AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G08G1/00 

FIELD: transportation.

SUBSTANCE: invention relates to the railway automatic systems and telemechanics. The device, that implements a method of operating a lens traffic light comprises a source of alternating voltage, a transformer, three diode OR gate, two elements AND a switch, one of which is polarized with two windings, one end of which is connected to the ground, and the other - to the outputs of the elements AND, some inputs of which are respectively connected to the cathodes of the first and second diodes, whose anodes are respectively connected to the closed and open contacts polarized relay changeover contact is connected to the ground, while others are combined and connected to the output of the first element OR the one, whose first input through normally closed contacts a third switch is connected to the cathode of the diode. Wherein the relay coil and the primary winding of the transformer are connected in series and connected to an AC voltage source. The device is further provided with a second element OR the one, whose inputs are respectively connected to the outputs of gate elements AND, an output connected to the first data output device, with a second input of the first element OR gate and the cathode of the third diode.

EFFECT: invention enhances the performance characteristics of railway automatic system.
